Questions & Answers
Do I need the 18 or 16 TPI for the Wilson Combat BILLet-AR-10 receiver? Expert Answer

Wilson Combat does not state the threads of that upper receiver. From what information I could find you will need the 16TPI model of the Lancer Systems LCH7 Octagon Carbon Fiber Handguards. However, I recommend contacting Wilson Combat to confirm compatibility.

Will this work with a slr straight pistol length gas tube and jet adjustable gas block? Where the tube meets gas block is raised to keep straight tube Expert Answer

Yes. The Lancer Systems LCH7 Octagon Carbon Fiber Handguards feature an inside diameter of 1.89", making it compatible with most adjustable gas blocks.

Solid hand guard by Derrick, Verified Owner, October 7, 2022
Install was fairly easy, just make sure you have the proper tools readily available. Follow the instructions and you’ll be set. It’s light but as others have said it’s not too big of a difference in weight compared to the aluminum hand guards. Just b...

Design flaws by Julio, December 31, 2020
The weakness of the handguard is the mounting of the handguard. The handguard is bolted to the mount. However, this only works if the handguard is a very tight fit to the mount. Return the handguard if it is oversized for the mount, or tighten the...

Lightweight & Sturdy by torval, Verified Owner, November 28, 2025
Purchased this to mirror my WWSD 5.56 build. It's lightweight and sturdy. It came pre-assembled and needed to be disassembled to install onto the upper receiver. The instructions are clear.

Product Info for Lancer Systems LCH7 Octagon Carbon Fiber Handguards

The LCH7 is Lancer's flagship free-floating carbon fiber handguard which has been painstakingly engineered to reduce weight while improving the overall strength and accuracy of the AR-10 platform. Contrary to popular belief, we designed these handguards in carbon fiber not for cosmetic reasons, but because our carbon fiber handguards are lighter, stronger, and less heat-conductive than their aluminum counterparts. While they are certainly one of the best options on the market for competition use, they are much more than just "go-fast parts". The immense strength, durability, and low thermal conductivity of Lancer's carbon fiber handguards have made them the favored handguard system for some of the most demanding military units and law enforcement agencies both in the United States and in our allied countries around the globe.image

NOTE: The proprietary free-floating handguard mount requires the removal of the barrel and specialized knowledge of the AR-10 platform for successful installation and removal. Fixed front sight posts and gas blocks may also need to be removed during installation. If you're not comfortable performing these tasks on your rifle system, please consult a certified gunsmith for professional installation.
